Can you figure this out?

NO CHEATING PLEASE!

​

Professor Ron wants you to make up a math problem using seven 7's and one minus sign to arrive to the answer "7".










I never figured this out on my own, I finally had to give in. I will tell you once someone gets the answer correct or after a few days if no one was able to figure it out. Good luck!

You can use numbers other than 7 right...

 

[tasha41]

(77 / 77) + (747-741) = 7

or is that cheating with brackets lol --> the / is a division symbol?

 

[shaunanicole]

Sorry hun, you MUST use only 7's and seven of them in the problem. (No other numbers and there must be a total of seven 7's.)

 

[tasha41]

Oooh okay I'll get thinking on it lol.

 

[Mynx]

Ok this is probably way off but here goes

7 + 7 - 7 x 7 / 7 x 7 / 7 = 7

(couldnt find teh division sign on keyboard lol hence the / instead!)

 

[shaunanicole]

You can only use ONE minus sign in the problem. No other signs.

Umm I got

7+7-7x7 / 7x7 / 7= 7

/ because I have no divide symbol on my laptop

 

[AppleBlossom]

Ok this is probably way off but here goes

7 + 7 - 7 x 7 / 7 x 7 / 7 = 7

(couldnt find teh division sign on keyboard lol hence the / instead!)

Ooh same as mine!!

Can you use decimals?

 

[Michy]

or fractions?

 

[tasha41]

Yes you could do

7.777 - .777 = 7 if you can use decimals...

 

[Michy]

yes that is what I meant, you can do something similar with fractions too

Ok this is probably way off but here goes

7 + 7 - 7 x 7 / 7 x 7 / 7 = 7

Great minds eh
